AMSOIL Synthetic Motorcycle Oil - Rust Protection

Rust protection is particularly important in motorcycle applications.

Motorcycle engines are more susceptible to corrosion and rust than automobiles. Often used seasonally, then stored and unused for extended periods of time, condensation and moisture within the engine promote rust formation. In addition, the combustion process and short trip driving create condensation and acids that further promote corrosion and rust.

Because it is as abrasive as dirt, rust causes a myriad of problems, including scratching and pitting on cylinders, pistons and bearing surfaces, leading to blow-by, lower compression and reduced power and performance. When rust forms on Harley-Davidson needle bearings, bearing failure results. Rust also causes excessive wear on bearings, camshafts, lifters and gear surfaces.

Motor oil has little or no natural ability to prevent rust and cannot provide rust protection on its own. It must be formulated with special rust inhibitors. However, because rust inhibitors typically sacrifice wear protection by competing with anti-wear additives for the metal surface, many motorcycle oils are formulated without rust inhibitors. AMSOIL Synthetic Motorcycle Oils are formulated with breakthrough technology not previously available, providing outstanding protection against rust without sacrificing wear protection.

The ASTM D-1748 Rust Test (humidity cabinet test) measures a lubricant's ability to protect against rust and corrosion. A standard metal reference coupon (metal plate) is immersed in the test oil before being placed in a humidity cabinet for 24 hours at 120 degrees F. Following the test period, the coupons are removed and inspected for rust. In order to pass the test, an oil may allow no more than three rust spots less than or equal to 1 mm in diameter. Oils allowing more than three rust spots, or one rust spot larger than 1 mm diameter, fail the test.

Two separate tests were performed. One test for SAE 40 and one for SAE 50 oils. Failing oils were divided into three categories: oils showing 1-10 spots, oils showing 11-20 spots and oils showing over 20 spots.

Both AMSOIL 10W-40 Synthetic Motorcycle Oil (MCF) and AMSOIL 20W-50 Synthetic Motorcycle Oil (MCV) showed no rust spots, placing them at the top of their respective test groups. Many competing motorcycle oils failed the test. AMSOIL Synthetic Motorcycle Oils provide unsurpassed rust protection, allowing motorcycles to perform better, last longer and require less maintenance.

What You Need To Know About Motorcycle Oils

Overview
As with any vehicle equipped with an internal combustion engine, proper lubrication is essential to insure performance and longevity. It is important to point out that not all internal combustion engines are similarly designed or exposed to the same types of operation. These variations in design and operation place different demands on engine oils. Specifically, the demands placed on motorcycle engine oils are more severe than those placed on automotive engine oils. Therefore, the performance requirements of motorcycle oils are more demanding as well.

Though the degree may be debatable, few will disagree that a difference exists between automotive and motorcycle applications. In which area these differences are and to what degree they alter lubrication requirements are not clear to most motorcycle operators. By comparing some basic equipment information, one can better understand the differences that exist.

There are six primary differences between motorcycle and automotive engine applications:

Operational Speed - Motorcycles tend to operate at engine speeds significantly higher than automobiles. This places additional stress on engine components, increasing the need for wear protection. It also subjects lubricating oils to higher loading and shear forces. Elevated operating RPMs also promote foaming, which can reduce an oil's load-carrying ability and accelerated oxidation.

Compression Ratio - Motorcycles tend to operate with higher engine compression ratios than automobiles. Higher compression ratios place additional stress on engine components and increase engine operating temperatures. Higher demands are placed on the oil to reduce wear. Elevated operating temperatures also promote thermal degradation of the oil, reducing its life expectancy and increasing the formation of internal engine deposits.

Horsepower/Displacement Density - Motorcycle engines produce nearly twice the horsepower per cubic inch of displacement of automobile engines. This exposes the lubricating oil to higher temperatures and stress.

Variable Engine Cooling - In general, automotive applications usa a sophisticated water-cooling system to control engine operating temperatures. Similar systems can be found in motorcycle applications, but other designs also exist. Many motorcycles are air-cooled or use a combination air/oil design. Though effective, they result in greater fluctuations in operating temperatures, particularly when motorcycle are operated in stop-and-go traffic. Elevated operating temperature promotes oxidation and causes oils to thin, reducing their load carrying ability.

Multiple Lubrication Functionality - In automotive applications, engine oils are required to lubricate only the engine. Other automotive assemblies, such as transmissions, have seperate fluid reservoirs that contain a lubricant designed specifically for that component. The requirements of that fluid differ significantly from those of automotive engine oil. Many motorcycles have a common sump supplying oil to both the engine and transmission. In such cases, the oil is required to meet the needs of both the engine and transmission gears. Many motorcycles also incorporate a frictional clutch within the transmission that uses the same oil.

Inactivity - Motorcycles are typically used less frequently than automobiles. Whereas automobiles are used on a daily basis, motorcycle use is usually periodic and in many cases seasonal. These extended periods of inactivity place additional stress on motorcycle oils. In these circumstances, rust and acid corrosion protection are of critical concern.

It is apparent that motorcycle applications place a different set of requirements on lubricating oils. Motorcycle oils, therefore, must be formulated to address this unique set of high stress conditions.

AMSOIL Synthetic Dirt Bile Oil Maximizes Performance

Consistent Clutch Feel - Clutch slippage or inconsistent clutch feel can prevent dirt bike riders from riding as fast or effectively as they like. To keep the engine within the power band, riders often modulate the clutch, increasing the opportunity for clutch slippage if low-quality lubricants are used.

AMSOIL Synthetic Dirt Bike Oil's superior friction-durability properties help minimize clutch slippage, fade and chatter, giving riders consistent clutch feel during takeoffs or when maneuvering around obstacles on the trail. In an extreme simulated-start test, AMSOIL Synthetic Dirt Bike Oil continued to deliver consistent clutch feel following 32 simulated race starts, while a leading original equipment manufacturer (OEM)-branded oil demonstrated inconsistent clutch-lever action and poor clutch feel after 16 starts. The clutch plates lubricated with AMSOIL Synthetic Dirt Bike Oil remained clean and in good overall condition, while the plates using the OEM oil revealed discoloration and wear. AMSOIL Synthetic Dirt Bike Oil's superior performance helps instill in riders the confidence that their bikes will perform consistently in all types of riding conditions.

Racing is Research - AMSOIL corporately sponsored supercross and motocross racers identified consistent clutch feel as a key performance attribute. At the time, there was no dirt-bike-specific oil on the market that provided the level of clutch consistency professional and amateur riders demand. Consistent clutch feel is critical to motocross riders during starts to keep the bike from lurching forward prior to the gate dropping. Trail riders, meanwhile, need consistent clutch feel to confidently navigate obstacles without having to shift gears and lose momentum.

In-Depth Product Development - The process to develop Synthetic Dirt Bike Oil relied on a combination of lab and track testing. Clutch feel is inherently subjective, which creates challenges in designing a lubricant that delivers consistent clutch feel. To overcome that challenge, AMSOIL designed The Extreme Simulated-Start Test on Dirt Bikes. The test allows AMSOIL engineers to apply accelerated stress to a dirt bike's clutch in order to monitor clutch feel produced by a candidate lubricant.

The test uses a 2014 Honda CRF450R attached to a dyno. While in second gear, the test administrator holds the clutch at the point just prior to engagement, similar to the way a rider would hold the bike in the gates during a race start. The clutch is then released and the bike is run to fourth gear, simulating the time from the drop of the gate to the first corner in a race. The rear wheel is not allowed to slip during the test, placing additional stress on the clutch. Test administrators look for consistent lever action and feel as they wait to let out the clutch and as they shift the bike through the gears.

AMSOIL Synthetic Dirt Bike Oil was also subjected to extensive on-track testing in the bikes of GEICO/AMSOIL/Honda Factory Connection and other professional riders. A combination of rider feedback and lab testing resulted in the final formulation of Synthetic Dirt Bike Oil. Its performance in lab and track testing dispels the myth that synthetics are "too slippery" and make clutches slip. Results also demonstrate that AMSOIL Synthetic Dirt Bike Oil delivers consistent clutch performance while helping extend clutch life. (Buy Online)

NOACK Volatility Test is a Critical Measurement of Motor Oil Quality

AMSOIL was the first motor oil company in North America to use the NOACK volatility test to measure motor oil quality and performance. Although competing motor oil companies initially paid no attention to NOACK results, the test has since become a critical measurement tool throughout the industry.

Modern engine designs generate more heat than ever, accentuating the importance of the NOACK volatility test for determining an oil's ability to provide an adequate level of protection and performance. More horsepower, turbo chargers and aerodynamic styling have created extremely hot environments that receive less cooling from outside air, and high heat leads to oil oxidation, deposits and thickening in conventional oils.

Top quality for the current API SM motor oils specification, gasoline motor oils cannot experience a weight loss of more than 15 percent in the NOACK test. AMSOIL Synthetic Motor Oils were exceeding modern requirements over 20 years ago, while many current motor oils still have a hard time meeting this minimal requirement, increasing wear, fuel consumption and emissions.

As seen in the graph, AMSOIL Synthetic Motor Oil easily passes the NOACK Test and falls well below the the maximum 15 percent volatilization (burn off) rate dictated by the API SM motor oil specification, while the Royal Purple volatilization (burn off) rate is over 11 percent and the Lucas Oil FAILS the test with a volatilization (burn off) rate of over 40 percent.

With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.


Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.


THE NOACK Volatility Test
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. AMSOIL Synthetic Motor Oil resists high temperature volatization better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.
